This paper provides evidence that shifts in the occupational composition of the U.S. workforce are the most important factor explaining the trend decline in the labor share over the past four decades. Estimates suggest that while there is unitary elasticity between equipment capital and non-routine tasks, equipment capital and routine tasks are highly substitutable. Through the lenses of a general equilibrium model with occupational choice and the estimated production technology, I document that the fall in relative price of equipment capital alone can explain 72 percent of the observed decline in the U.S. labor share. In addition, I find that differences in labor share trends across sectors can be accounted for by varying sensitivities of cost of production to the price of equipment capital.

This dissertation studies the impact of technological progress on various aspects of the U.S. labor markets such as the recent decline in the labor's share of income, job and wage polarization, rising income and wealth inequalities and skill accumulation. Chapter 1, "Capital-Task Complementarity and the Decline of the U.S. Labor Share of Income," studies how changes in occupational composition of the labor force contributes to the recent decline of the US labor share of income. Following the job polarization literature and classifying labor by tasks performed, I estimate unitary elasticity between equipment capital and labor performing non-routine tasks. This implies that income loss of labor em- ployed in routine task occupations is the main driver of the decline of the aggregate labor share. For a given path of technological change, decline of the labor share is larger when: (i) the substitutability between equipment capital and routine tasks is stronger, and (ii) equip- ment capital has a larger weight in production. Furthermore, a dynamic general equilibrium model shows that the impact of permanent technology shocks on the labor share gets smaller as the fraction of routine task labor declines. Consistent with this, the model predicts that the labor share should stabilize at around 55% in the long-run even if technological progress continues at its current pace. The model also documents that the fall in relative equipment capital prices alone can explain 72% of the decline of the labor share for the 1967-2013 period. Finally, repeating the analysis by disaggregating labor into educational groups reveals that the theory based on capital-task interactions improves on the capital-skill complementarity theory in explaining the decline of the labor share. Chapter 2, "Impact of Information Technology on the Labor Share: Evidence from the U.S. Sectoral Data," contributes to the debate over the relationship between capital deep- ening and the aggregate labor share from a sectoral perspective. The study focuses on a specific group of equipment capital: information and communication technology (ICT) capital and exploits various sectoral heterogeneities to characterize the conditions under which the surge in ICT capital cause the labor share to fall. First, I document significant capital- task complementarity at each sector. Second, decline in ICT capital prices turns out to have a positive impact on the labor share. However, gains of labor devoted to non-routine task occupations are offset by the losses of labor employed in routine task occupations when a sector has: (i) initially high load of employment in routine task occupations, and (ii) weak absolute complementarity between ICT capital and labor working in occupations associated with non-routine tasks. Since sectors satisfying these two conditions have compromised the majority of the economy, the aggregate labor share has exhibited a downward trend so far, leading to the illusion that information technology has been driving the labor share downwards. However, there are two promising facts concerning the future: in one hand, the share of these sectors in value added is persistently falling and on the other hand, the share of routine task employment continues to fall at every sector. Thus, once the structural shifts and within sectoral adjustments are completed, the decline in the labor share should revert back. Chapter 3, "Job Polarization, Skill Accumulation and Wealth Inequality," is one of the first attempts in literature to incorporate the job polarization idea into an otherwise standard incomplete markets model with heterogeneous agents in two dimensions: skills and idiosyn- cratic productivity shocks. This set up allows us to contribute to the existing literature in two ways: (i) linking job polarization with rising wealth concentration, and (ii) modeling the continuous rise in skill supply in response to technological progress and job polarization accompanying it over time. When calibrated and solved for the years 1981 and 2011, the model shows that the decline in relative computer (ICT) capital prices alone accounts for a significant portion of the increases in employment share and relative wages of high skill occupations, as well as the increase in the supply of labor with a college or above-college degree. Consistent with the routinization hypothesis, the model also shows that advances in computer technology can account for most of the decline of the employment share and rela- tive wage of middle class over the three decades between 1981 and 2011. Furthermore, the model successfully captures the erosion of middle-class wealth, whereas wealth concentration rises substantially at the right tail and slightly at the left tail of the wealth distribution.

The role of capital accumulation as a driver of the labor income share requires capital and labor to be substitutes, which appears paradoxical in a world predominantly characterized by complementarity between capital and labor. This paper argues that the composition of skills in the labor force and an identification of the elasticity parameters between capital and different skills of labor can reconcile the opposing views. Using a framework with capital-skill complementarity and variable substitution elasticities, the Morishima elasticity of substitution is applied to identify the elasticity parameters at different skill levels and derive the necessary condition for capital accumulation to coexist with a declining labor income share when capital and labor are complements. Empirical evidence supports this proposition.

Handbook of Macroeconomics Volumes 2A and 2B surveys major advances in macroeconomic scholarship since the publication of Volume 1 (1999), carefully distinguishing between empirical, theoretical, methodological, and policy issues, including fiscal, monetary, and regulatory policies to deal with crises, unemployment, and economic growth. As this volume shows, macroeconomics has undergone a profound change since the publication of the last volume, due in no small part to the questions thrust into the spotlight by the worldwide financial crisis of 2008. With contributions from the world’s leading macroeconomists, its reevaluation of macroeconomic scholarship and assessment of its future constitute an investment worth making. Serves a double role as a textbook for macroeconomics courses and as a gateway for students to the latest research Acts as a one-of-a-kind resource as no major collections of macroeconomic essays have been published in the last decade Builds upon Volume 1 by using its section headings to illustrate just how far macroeconomic thought has evolved

This book focuses on the specific traits and nature of entrepreneurial human capital and the extent to which it can be stimulated by entrepreneurship education – especially when these activities combine collaborative practices and innovation. It includes a comprehensive collection of articles on how entrepreneurship education can be structured, providing theoretical reflections as well as empirical evidence. As such it contributes to the ongoing debate on the teachability of entrepreneurial skills and the role of innovation and collaboration in the design of educational programs that aim to spread entrepreneurial human capital.

This study provides evidence for the US that the secular decline in the labor share is not only explained by technical change or globalization, but also by the dynamics of factor taxation, automation capital (robots), and population growth. First, we empirically find indications of co-integration for the period from the last quarter of the 20th to the first decade of the 21st century. Permanent effects on factor shares emanate from relative factor taxation. The latter also have a lasting effect on the use of robots. Variance decompositions reveal that taxing contributes to changes in the two income shares and in automation capital. Second, we analyse and calibrate a neoclassical growth model extended to include factor taxation, automation capital, and capital adjustment costs. Labor and automation capital are perfect substitutes whereas labor and traditional capital are complements. The model replicates the dynamics of the observed functional income distribution in the US during the 1965-2015 period. Counterfactual experiments suggest that the fall in the labor share would have been significantly smaller if labor and capital income tax rates had remained at their respective level of the 1960s.

Globally, the share of income going to labor (the “labor income share”) is declining. However, this aggregate decline hides more than it reveals. While the labor income share has decreased for low-skilled workers, this has been concurrent with an increase for high-skilled workers. Globalization leading to a growing skill premium and an increasing complementarity between capital and skill through the advancement of technology explains the polarization of labor income shares across the skill spectrum.

This paper revisits capital-skill complementarity and inequality, as in Krusell, Ohanian, Rios-Rull and Violante (KORV, 2000). Using their methodology, we study how well the KORV model accounts for more recent data, including the large changes in labor's share of income that were not present in KORV. We study both labor share of gross income (as in KORV), and income net of depreciation. We also use non-farm business sector output as an alternative measure of production to real GDP. We find strong evidence for continued capital-skill complementarity in the most recent data, and that the model continues to closely account for the skill premium. The model captures the average level of labor share, though it overpredicts its level by 2-4 percentage points at the end of the period.

This paper shows that the decline in the labor share over the last 30 years was not offset by an increase in the capital share. I calculate payments to capital as the product of the required rate of return on capital and the value of the capital stock. I document a large decline in the capital share and a large increase in the profit share in the U.S. non-financial corporate sector over the last 30 years. I show that the decline in the capital share is robust to many calculations of the required rate of return and is unlikely to be driven by unobserved capital. I interpret these results through the lens of a standard general equilibrium model, and I show that only an increase in markups can generate a simultaneous decline in the shares of both labor and capital. I provide reduced form empirical evidence that an increase in markups plays a significant role in the decline in the labor share. These results suggest that the decline in the shares of labor and capital are due to an increase in markups and call into question the conclusion that the decline in the labor share is an efficient outcome.
